IPC: H02P8/12
Filed: 1982-12-13
Abstract: PURPOSE:To stably rotate a pulse motor under the low speed rotating condition of the motor by chopping corresponding to the drive time at the excited 2- phase side or the overdrive voltage side, thereby preventing the generation of an abnormal current. CONSTITUTION:The current of a drive power source E is converted by a pulse motor drive circuit 1 into a pulse voltage, the pulse application period is varied, and a pulse motor 2 is rotated by applying it to the 2-phase coils of the motor 2 through an overdrive circuit switch S1 and the phase switches S2-S5 of the motor. Chopping T3 is performed for the overdrive time T2 to the 2-phase coil excited in the range of the pulse application period T1 when the swtiches S2- S5 are switched under the low speed rotating condition of the motor 2. Thus, the application of the time pulse voltage of the chopping T3 is instantaneously interrupted, a current (i) is lowered simultaneously when the excitation of the 2-phase coils are released, thereby preventing the application of the abnormal current thereto to perform stable low speed rotation of the motor.
